navigation system AUDI A4 1995 B5 / 1.G Multi Functions Steering Wheel Workshop Manual

91-70

Function description:
For better operation of radio and telephone
system while driving, six function keys are
integrated into the steering wheel. In addition, the
multi-function steering wheel is electrically
heated.
The electronics in the steering wheel take over
the regulation of the steering wheel heating,
transmission of the six function buttons to CAN-
bus and dimming of the function buttons. The
electronics in the steering wheel cannot be
replaced individually, the entire steering wheel
must be replaced in case of a malfunction.
The control module of the multi-function steering
wheel takes over control of the radio (or
radio/navigation system), telephone system,
instrument cluster, and steering wheel heating.
In the center display of the instrument cluster, the
selected station appears during radio operation
and the name and telephone number of the
dialogue partner from the telephone memory
appears during telephone operation. If a cassette
is inserted during radio operation, the message
"TAPE " appears and for CD-operation, CD-
number "CD 02" and the respective title (track)
"TR 09" appears on the center display.
